The Schedule referred, to in these Letters Patent and making part of thesame To `all whom it may concer-ir: t

Be it -knownsthat I, J om: Bonn, of the city'of Grand Rapids, "Michigan,have invented certain new and useful Improvements in PaperandCard-Outting Machines; `and I'do hereby declare that the following lis a full, clear,`and exact ldescription of my invention, lrefercnce'being had "tothe accompanying drawing and theletters ofreference marked thereon, and the same u gare made apartgofl thesespecificationse The figure represents a general view of my invention iners ectne when constructed and read for av y y y The flame-work ofthemachine,.shown in the figureiby the` letters' A'A,` may be constructedof wood or any othersuitable material.

The part represented in the iignre by letters e e e and E is a strongti-ame,composed of iron or som'e suit-able material, and is moved upwardand downward `whenthe machine is infoper'atiom d t-hat bar. l

. d is a vbeveled cog-wheel attached to the screw Sin such a manner asto revolve with it, and c is a perpendicular beveled cog-wheel, whichengages with the cog-wheel d. i

y B is an ordinary hand crank-wheel. provided with the handle t. l Thiswheel `is`1 connected with the part c `by means `.of a strong rod, n. l

In 'the `figure, letters hand k represent adjustable gauges. i i i e Thegaugeph is made to fit into the grooves, as

rshown in the figure. `The gauge k is attached to two rectangular stripsof iron, shown in the figure by :t qs,

which slide under the table of the machine.

is held in its place by means of the thumb-nuts lm m; t

In cutting cards with my invention, the card-board is placed upon thetable and passed under the knife until it meets with the gauge k.

Then, by revolving the wheel B, the wheelsc and d are put in motion, andthe part R of the frame is presseddownward by the revolution of thelscrew S, thus drawing the knife a with great power uponthe card-board,easily cutting through a large number of cards at the same time, whenythe card-boards are cnt into strips of the width corresponding with thelength of the cards desired.

The gauge 1c is regulated tothe required distance, and the strips areplaced against the gauge It, passed under the knife until they meet thegauge k, andthe knife lowered a-s above described.

In cutting paper with my machine, the gauges h and kare removed, and anordinary flat table is placed upon the top of the machine. The paper tobe cut is placed under the knife, and the knife lowered as abovedescribed.

The cutting power of the machine may be increased by increasing the sizeor circumference of the .cog-

wheel d, or by diminishing the circumference of the through thecross-bar, firmly connected to the bevel? wheel d, and operated by thebevel-wheel c upon the haft mand the crank-wheel B, substantially as setorth. Y y
